Check the nylon cup on the end of the speedo drive gearbox. Sometimes they get damaged and don't engage the sprocket bolt.

I don't see a nylon cup when I take the cable out the drive.Just metal piece which the cable slots over.

You need to unbolt the speedo drive from the front sprocket cover. Theres a nylon fitting there that tends to break - sometimes a sign that your speedo drive itself is a bit stiff and needs lubrication

Seems to be trying to work moving a little then dying again.

Nylon cup looks okay and when I spin it the speedo needle moves a little.What do I lubricate and with what?

the cable with spray grease(but not the top 4 inchs by speedo)or wd40,and the end with the same or normal hmp grease.

On closer inspection the nylon cup does look rounded off.Got a new one and fitting tomorrow.
